This summarizes all of the very helpful and rapid responses to my recent
query regarding inexpensive or freely available software for analysing
spatial data. I am still sorting through the URLs that were recommended.
This kind of helpful, worldwide support is a wonderful reminder of the
best of the internet (a reminder that for me is necessary time to
time!). THANK YOU all.
I have left addresses in so that you might contact respondents for any
clarification. Hope I am not violating a rule but this is open so assume
it is Ok. Correct me pls if not, for future reference.:)zf

Hi Zack,
SPSS Science have a student version of SYSTAT (£125 plus carriage &
VAT).
This is a very good package, and has various spatial statistics options
including Kriging (simple, ordinary, nonstationary & drift). They will
sell
it to anyone in academia (not just students), but it appears it is only
for
home use.
Antro.

Hi. GeoR might be what you're looking for.
http://www.maths.lancs.ac.uk/~ribeiro/geoS.html
it's a plublic domain package for R (a public domain statistical
package),
and it's available for windows.
bye.

Try R which can be downloaded from lib.stat.cmu.edu You will also need
the
spatial statistics package.
Best, Mark Hall

Hi,
1. Try http://www.freegis.org , there may be something interesting
there.
2. Try http://lib.stat.cmu.edu/R/CRAN/ for details of the R language
("not unlike S" the language underpinning S-Plus), which is released
under
the GPL, also called "copylefting" (I think). This is not public
domain
software, but all the software can be downloaded at no cost (see
http://www.fsf.org for more details on that sort of thing). If you
hunt
around the R site you will find contributed extensions which allow you
to
run a number of the spatial models you want. If you hunt around the
recent
archives of the mailing list you will also find a couple of other
authors
who have extensions on their websites, but I think these are source code
only.
There are windows binaries available for R, and some extensions you will
be
interested in are also available as windows binaries, all of which can
be
installed by a simple installer program (all on the website). As the
main
development is in Unix / GNU Linux you may find useful stuff available
as
source code rather than windows binaries, but again, hunting round the
website will lead you to all the widgets and wodgets you need to compile
your own if you get that keen. There's a link between R and the GIS
GRASS,
but I haven't yet fired that up yet (last time I looked GRASS hadn't
been
fully ported to Windows and my GNU / Linux machine is too full).
Hope that helps. S-Plus with the Spatial Stats module is one other
choice, being a commercial venture you get loads of pointy-clicky stuff,
and
you don't have to hunt around collecting all the functions you might be
interested in (and you get trellis graphs).
Regards

Don't know what you need exactly - but you might wish to try
out
XLisp-Stat (http://lib.stat.cmu.edu/xlispstat)
and
R (don't know where you might get it from)
Both, so I gather, have interesting graphical features.
And they are both free.
Hope this helps.

Zack,
I would recommend you to visit the web address:
www.ai-geostats.org
There you'll find lots of information about commercial and free
software for spatial analyses.

Here is a response from a colleague involved in spatial analysis of soil
properties.
Probably the best option is WinGSLIB. A licence for the software is
available for about
USD 250. See www.gslib.com
What GSLIB won't do is fit a model to point estimates of the variogram.
One
useful Windows program which will do this, and some other interesting
analyses besides, is VESPER (University of Sydney) This is free - see

dear zack,
i would recommend you GSTAT. GSTAT is a computer program for
geostatistical
modelling, prediction and simulation.
Gstat works at least on the following platforms: Linux, hp-ux (9.x,
10.x),
aix (3.2, 4.1), OSF/Alpha, SunOS, SGI, win32 and MS-DOS (dpmi). Gstat is
Open Source software, so you can avoid some problems associated with
microsoft. free download is available at following location:
http://www.geog.uu.nl/gstat/

Please check out the EcoSSe software (Eco Spatial Statistical
Evaluation)
software.
Price $US1,000 via Web purchasing at http://geoecosse.hypermart.net
600 pounds Sterling (just over 1,000 Euros) plus VAT where applicable.
Order
from http://geoecosse.bizland.com/enq.htm
Demo version available at
http://uk.geocities.com/drisobelclark/Ecosse_download.html
This software also forms an integral part of the new book (2 months!)
Practical Geostatistics 2000 by myself and Bill Harper. It is a full
Windows
implementation (95, 98 and 2000) and includes some basic statistical
analysis, semi-variogram calculation and modelling and kriging
(ordinary,
lognormal, indicator, universal, rank uniform). Updates until the end of
2000 are included in the price and include co-kriging and even more
interactive graphics.
The only cheaper you will find is GS+ which is around $500 and can be
found
by any search engine on the keywords geostatistics and software.
There is free and shareware stuff around, but I don't know of any true
Windows implementation. There is, for example, a Windows shell for
GSLIB,
but this just opens a DOS Window.
Please feel free to contact me or Bill Harper [log in to unmask] if
you
have any detailed questions.
